| Abstract Scope |
Reinforced concrete structures require frequent repair and maintenance, resulting in significant costs and CO2 emissions associated with them. To address this issue, a durable self-healing concrete incorporating the enzyme Carbonic Anhydrase (CA) was introduced. A series of tests comparing control and CA-modified mixtures was conducted to assess the impact of CA on the durability of concrete using water/chloride permeability and corrosion tests. To overcome the limitations of existing permeability tests, a vacuum-assisted accelerated method was developed. Results indicate that CA-modified specimens exhibited a significant reduction (~50%) in dye adsorption, demonstrating enhanced durability and extended service life. Moreover, the CA-modified specimens displayed improved corrosion resistance under adverse conditions without compromising the mechanical properties of concrete, making ACT a promising technique. |
